- Description
- The CALS Raster Graphic File, having the extension .cals, is a type of image file format primarily used for the storage and exchange of digital images, especially in the context of technical and engineering documents. Developed in the mid-1980s by the United States Department of Defense, the CALS format was part of an initiative to standardize electronic document management and interchange, particularly for military and government applications.
- The PGX file format is associated with Hopedot VOS, a virtual operating system software that allows users to run a separate operating environment on their computers, similar to virtualization technologies. A PGX file typically contains data related to the Hopedot VOS environment, such as settings, applications, and other user-specific information.
